My freezer stopped working, ice has been building up by the drain for some time. thiis time I may have overloaded the fridge and it is difficukt to see if the door is closed properly as it is attached to a cabinet door. I have now defrosteed it and after 24 hours seems to be functioning, but I would like to read suggested temperature control etc etc, I found the balance of fridge and freezer balance hard to understand.
